1: The audio is not in the PMT table (minor issue possibly caused by #2)
2: PTS information in the MPEG-TS is completely messed up/missing.  
(Project X recreates and resynchronizes the audio PTS)

I believe you cannot simply convert MPEG1 -> MPEG2-TS. it might work  
by accident, but MPEG1 is quite different then MPEG2-PS.
